Unify packaging: use Docker + fpm for DEB and RPM builds

- Add Dockerfile.package with multi-stage build (builder, package-builder, output)
- Update Makefile to use new Dockerfile.package for package-deb and package-rpm targets
- Replace dpkg-deb and rpmbuild with fpm for consistent packaging
- Both DEB and RPM packages now built from single Dockerfile
